Thirteen Bands - what a woolly bear's stripes really say

Found a fuzzy black-and-rust caterpillar? Tap its 13 segments to paint the bands you saw; the page counts them, checks for look-alike signs and says whether to leave it, move it a little or check what it is first - free. One metered reading weighs four explanations (its age, how long it has fed, a different caterpillar, the winter folklore) against your entry and says what would tell them apart. It never forecasts the weather. Built on the SkillSafe skill @89jobrien/meta-cognitive-reasoning.
